Will using this jumper cause damage to an electrical system/computer on newer cars e.g. 2008 Toyota Highlander?

Probably not considering a jump from a AAA roadside guy is a stronger potential difference.

I don't know, you may want to contact the manufacture. If you want my opinion, here it is: If you are stalled somewhere and can't get your car started, don't you need something that can get it started? If you call AAA or a towing service, how do you know that their jumper will cause you damage. The point is, you need a start and I recommend this for ME.

I would not bet on it. The only time that I tried this was on a diesel pick up truck with a jump start battery pack helping it and I still didn't get it started. What worked was a battery charger with a built in engine starter. This porta jump seems weaker than advertized...just my experience.

Yes. As long as you are jump starting it with a battery in your car and near a power outlet to plug this in.

This could be a security or safety feature of the car itself. If the adapter works fine after you start the car then I don't see a reason why you should return it. In any case it is your call.

That cord is meant for recharging the unit not to jump start a car, You can not jump start any car that way with any product (only charge). The only thing you can do is do a slow low amp charge through the auxiliary power outlet ( I am a ASE certified tech and have seen people do much harm to the cars power outlet) Like others have said that outlet is fused and the biggest fuse I have seen is a 20 amp on that circuit, that is not enough amps to start a car.

Should be no problem as it hooks to the electrical system and is on when you turn car on or flip the switch to turn it on of you decide to wire it that way.It does make an audible ton that is heard in the car.

If you meant leaving it ON inside the car, then there's a huge possibility that the battery would explode, not to mention, it would possibly fry some components in it. That's why I replaced the battery with a super capacitor.

I doubt it - it has not affected my 2012 Toyota's electronics. My understanding is that it senses disturbances in the magnetic field caused by the passage of large metal objects (vehicles). Its radio signal to the receiver should be nothing worse than any radio signals from things like walkie talkies and cell phones already in the environment.

thats not good. its a cheap replacement, dont ruin your car electrical system!

This Product is meant to be used with a remote start and alarm system. It is not meant to fix problems with your vehicle. It sounds like your GM vehicle has the usual problem with the Ignition Cylinder. On a GM car, as the Ignition cylinder turns with the key, the body computer senses the amount of resistance that is built into the Ign. Cyl. in ohms, so the computer can turn the electric fuel pump on, this was built in to prevent theft. On the GM Ign. Cyl., there are 2 small wires that have a little pigtail and plug, what usually happens after many years of turning the Ign. cyl. on and off, one or both of those wires breaks, on the inside, you can not see the break. That is why sometimes it starts for you, sometimes the wire makes the connection, sometimes, not. As you turn the Ign. Cyl., those 2 wires move back and forth, they break after time.

No! It is really an extension of the cigarette lighter socket, the wires are not heavy duty to jump start.

Not to run contrary to the folks providing all the technical expertise, but I have personally jumped my own car (4 cyl engine) from a rechargeable unit much less sophisticated than this AND plugged into the cigarette lighter/aux socket. Again, it was not this particular unit and, per the instructions, you had to wait several minutes. But it worked perfectly.

If the MAF is giving you a check light on the dash from being dirty than yes I would disconnect to reset the ECU. Other than that it depends on the make and model whether it's recommended. Disconnecting could never hurt though.

Hello, Yes, as long as the AC volts and DC volts match your system this device will be safe to use. When we talk about the amperage increase on this device we are talking about how quickly it can charge your battery bank and how many appliances can be used. If your system is properly fused, wired, and has appropriately sized batteries then an increase in amperage will be a benefit to your system. However a 5 amp increase will barely be noticeable in your system. One last little tip. Any charge controller like these (multi-mode) must be installed really darn close to the battery bank in order to provide a full charge to the batteries. Most people just put this device where the old one was pulled out because the wires are right there and it powers the coach from there so you think its good but thats generally a bad move because the wires that go from the power distribution box could be over 10' long before they get to the batteries. This length causes the wires to generate resistance and loose voltage that is essential to fully charge the batteries as a result your batteries will only really be 80% charged. So when installing this do not follow the path given by the manufacturer, move the unit so the DC cables are no longer than 4'-6' to reach the batteries and use as big of a cable as you can fit on this device (2-4AWG.) It does not matter how long the AC wires are as long as they are the right gauge. Good luck.

I used it to jump my Ford 5.0 V-8 and it worked. I forgot to plug it in to keep charging (you can leave the new ones plugged in all the time) and when i needed it again a month and a half later it didn't have enough power to jump the car. I plugged it in for 4 hours and not only jumped the car, but was able to use it as the battery while we did some repairs to the ignition system. It has plenty of power. There may be smaller amp jump starters that will work, but if they don't you may as well have nothing. This thing works.

OldAmazonian says:~{Gadgets like this can typically be kept topped up with a jumper from the car's lighter socket to the gadget's lighter socket. The better cords for the purpose have fuses in their plugs.

This depends on the amp load necessary for the jump. In most cases, I would say no. These cables are designed for two amps. Jumping can require up to 600-1000 amps and would likely melt the cable. M/C and ATV batteries require less but likely still more than this cable is capable of sustaining. Since ATVs and motorcycles use low amp alternators, it would likely work as a charger allowing the running vehicle to charge the dead battery. This would not work for large vehicles (cars, trucks, etc.) as their alternators put out 60 - 150 amps.
